Two more questions: No Crosses on your Ward or Temple buildings, but the statue Moroni is at the top of many Temples. Why Moroni and not Jesus ( or crosses )? I have assumed Moroni is heralding the second coming of Christ, is there significance to the direction He faces atop the Temples?
Response
In the book of revelation, the Apostle John said (Rev. 14:6) "And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth…" That angel was Moroni, and his place on the top of the temple is significant because of his participation in the restoration of the gospel to the earth in these latter days.
You also asked if there was significance to the direction Moroni faces atop the temples. There is. The direction is east and that is the direction from which the Savior will come as we see Him when He comes in power and glory (Ezek. 43:1-4).
